Administration of Cross-State Air Pollution Rule Trading Program Assurance Provisions for 2020 Control Periods Environmental Protection Agency EPA.
ACTION: Notice of data availability.
AGENCY:

The Environmental Protection Agency EPA is providing notice of the availability of data on the administration of the assurance provisions of the Cross-State Air Pollution Rule CSAPR trading programs for the control periods in 2020. Total emissions of nitrogen oxides NOX reported by Mississippi and Missouri units participating in the CSAPR NOX Ozone Season Group 2
Trading Program during the 2020
control period exceeded the respective states assurance levels under the program. Data demonstrating the exceedances and EPAs final calculations of the amounts of additional allowances that the owners and operators of certain Mississippi and Missouri units must surrender have been posted in a spreadsheet on EPAs website.
DATES: September 22, 2021.
FOR FURTHER INFORMATION CONTACT:
Questions concerning this action should be addressed to Garrett Powers at 202
5642300 or powers.jamesg@epa.gov.
SUPPLEMENTARY INFORMATION: The regulations for each CSAPR trading program contain assurance provisions designed to ensure that the emissions reductions required from each state covered by the program occur within the state. If the total emissions from a given states affected units exceed the states assurance level under the program, then two allowances must be surrendered for each ton of emissions exceeding the assurance level in addition to the ordinary obligation to surrender one allowance for each ton of emissions. In the quarterly emissions reports covering the 2020 control period, Mississippi and Missouri units participating in the CSAPR NOX Ozone Season Group 2 Trading Program reported emissions that exceed the respective states assurance levels under the program. Mississippi units exceeded that states assurance level by 260 tons, resulting in a requirement for the surrender of 520 additional allowances, and Missouri units exceeded that states assurance level by 2,438 tons, resulting SUMMARY:
